ISO 639-3 in the context of "Provençal dialect"

Eblaite (/ˈɛblə.aɪt, ˈiːblə-/, also known as Eblan ISO 639-3), or Palaeosyrian, is an extinct East Semitic language used during the 3rd millennium BC in Northern Syria. It was named after the ancient city of Ebla, in modern western Syria. Variants of the language were also spoken in Mari and Nagar. According to Cyrus H. Gordon, although scribes might have spoken it sometimes, Eblaite was probably not spoken much, being rather a written lingua franca with East and West Semitic features.

The language was discovered through cuneiform tablets found in Ebla.

Rusyn (/ˈruːsɪn/ ROO-sin; Carpathian Rusyn: русиньскый язык, romanized: rusîn'skyj jazyk; Pannonian Rusyn: руски язик, romanized: ruski jazik) is an East Slavic language spoken by Rusyns in parts of Central and Eastern Europe, and written in the Cyrillic script. The majority of speakers live in Carpathian Ruthenia, which includes Transcarpathia and parts of eastern Slovakia and south-eastern Poland. There is also a sizeable Pannonian Rusyn linguistic island in Vojvodina, Serbia, and a Rusyn diaspora worldwide. Under the European Charter for Regional or Minority Languages, it is recognized as a protected minority language by Bosnia and Herzegovina, Croatia, Hungary, Romania, Poland (as Lemko), Serbia, and Slovakia.

The categorization of Rusyn as a language or dialect is a source of controversy. Czech, Slovak, and Hungarian, as well as American and some Polish and Serbian linguists treat it as a distinct language (with its own ISO 639-3 code), whereas other scholars (in Ukraine, Poland, Serbia, and Romania) treat it as a dialect of Ukrainian.

Silesian, occasionally called Upper Silesian, is an ethnolect of the Lechitic group spoken in Upper Silesia. While having secured some international recognition as a language, there is a debate on whether Silesian is either a dialect of Polish or a distinct language, and if Silesians are either a regional ethnic group within the Polish nation or a distinct ethnic minority that historically emerged, but later diverged from, the Polish people. Some Silesians identify as a regional ethnic group within the Polish nation, while others view themselves as a distinct ethnic minority. Its vocabulary was significantly influenced by Central German due to the existence of numerous Silesian German speakers in the area prior to World War II and after. The first mentions of Silesian as a distinct lect date back to the 16th century, and the first literature with Silesian characteristics to the 17th century.

Linguistic distinctiveness of Silesian has long been a topic of discussion among Poland's linguists, especially after all of Upper Silesia was included within the Polish borders following World War II. Some regard it as one of the four major dialects of Polish, while others classify it as a separate regional language, distinct from Polish. The dispute over the status of Silesian is considered to be of purely political character. According to the official data from the 2021 Polish census, 467 145 people use Silesian on daily basis. Internationally, Silesian has been fully recognized as a language since 2007, when it was accorded the ISO 639-3 registration code szl.

For a published list of languages, see ISO 639-1 (list of ISO 639 language codes for 136 major languages), or for a more inclusive list, see ISO 639-3 (list of ISO 639-3 codes, 7,874 in total as of June 2013). The enumeration of languages and dialects can easily be taken into the five-digit range; the Linguasphere Observatory has a database (LS-2010) with more than 32,800 coded entries and more than 70,900 linguistic names.

Wolaitta or Wolayttatto Doonaa is a North Omotic language of the Ometo group spoken in the Wolayita Zone and some other parts of southwestern Ethiopia. It is the native language of the Welayta people. The estimates of the population vary greatly because it is not agreed where the boundaries of the language are.

There are conflicting claims about how widely Wolaytta is spoken. Some hold that Melo, Oyda, and Gamo-Gofa-Dawro are also dialects, but most sources, including Ethnologue and ISO 639-3 now list these as separate languages. The different communities of speakers also recognize them as separate languages. A variety called Laha is said to be 'close' to Wolaytta in Hayward (1990) but listed as a distinct language by Blench; however, it is not included in Ethnologue.

A macrolanguage is a group of mutually intelligible speech varieties, or dialect continuum, that have no traditional name in common, and which may be considered distinct languages by their speakers. Macrolanguages are used as a book-keeping mechanism for the ISO 639 international standard of language codes. Macrolanguages are established to assist mapping between different sets of ISO language codes. Specifically, there may be a many-to-one correspondence between ISO 639-3, intended to identify all the thousands of languages of the world, and either of two other sets, ISO 639-1, established to identify languages in computer systems, and ISO 639-2, which encodes a few hundred languages for library cataloguing and bibliographic purposes. When such many-to-one ISO 639-2 codes are included in an ISO 639-3 context, they are called "macrolanguages" to distinguish them from the corresponding individual languages of ISO 639-3. According to the ISO,

ISO 639-3 is curated by SIL International; ISO 639-2 is curated by the Library of Congress (USA).

ISO 639 is a standardized nomenclature used to classify languages. Each language is assigned a two-letter (set 1) and three-letter lowercase abbreviation (sets 2–5). Part 1 of the standard, ISO 639-1, defines the two-letter codes, and Part 3 (2007), ISO 639-3, defines the three-letter codes, aiming to cover all known natural languages, largely superseding the ISO 639-2 three-letter code standard.
